...a detective does his job in the only possible way. He follows the requirements of the law to the letter -- or close enough so as not to jeopardize his case. Just as carefully, he ignores that law's spirit and intent. He becomes a salesman, a huckster as thieving and silver-tongued as any man who ever moved used cars or aluminum siding -- more so, in fact, when you consider that he's selling long prison terms to customers who have no genuine need for the product.
